Creative Tool
It doesn’t matter if you are a professional photographer looking for a lens for your next job, or an amateur looking to expand your focal range – the Irix 15mm f/2.4 is a right choice for every landscape photographer! The Irix 15mm f/2.4 lens is an ultra wide-angle lens created for your full frame (35mm) camera, available in Nikon F, Canon EF, and Pentax K mounts. This lens will allow you to open up to a completely new type of photography – thanks to the 110-degree field of view you will be able to capture eye-catching images, and the excellent optical properties will make the image sharp and full of details.

Compatible with filters

• What makes the Irix 15mm f/2.4 lens unique is the possibility of using both classic 95mm screw-on filters, as well as square filters, thanks to the Irix Edge IFH-100 holder!
• Every landscape photographer uses filters – they allow a creative approach to photography, which makes them extremely practical. The filters that you can use with the Irix 15mm f/2.4 lens are all 95mm filters, such as the Irix Edge:
• UV & Protector – protects your lens against damage
• Circular Polarizer – cuts off unwanted reflections and increase the clarity of the photo
• Neutral Density – decrease the amount of light reaching the camera sensor, thus allows, for example, creatively to blurs the motion in your photographs.
• Light Pollution – cuts off the light of cities, making your night photos full of detail without a yellowish haze
• Irix Edge IFH-100 Filter Holder allows you to expand your camera’s capabilities thanks to Gradual Neutral Density filters with different gradients: Soft, Hard and Reverse. By cutting off part of the light from the brightest part of the image, you can shoot even in the most difficult lighting conditions.

Perfect for night photography
Night photography is not only interesting but also highly rewarding – it allows you to easily create eye-catching images, if you have the right lens. The Irix 15mm f/2.4 is an irreplaceable tool for any astrophotographer – its fast aperture of f/2.4, combined with a short focal length allows you to capture spectacular shots of the night sky and the Milky Way. The night is yours!

Ready for Any Conditions
It doesn’t matter if you’re traversing the hot sands of the Sahara or the frigid expanse of Antarctica – Irix lenses never back down from any challenge. The sealing system has been designed to protect the inside of the lens from moisture, dust, and sand. Equally important, the lens does not change its dimensions during focus pulling, eliminating the risk of dirt particles getting swept into the internal structure. These properties not only allow you to work in demanding conditions, but also guarantee the cleanliness of the camera’s mirror chamber sensor.

Optics that guarantee sharp images
Creativity, ideas, and effort put into a photograph would be nothing without the right lens. Thanks to many years of experience in optical design, Irix lenses are characterized by their excellent resolution and minimal distortion (2%) and vignetting. The Irix 15mm f/2.4 lens consists of as many as 15 elements arranged in 11 groups: 4 refractive elements, 2 ED elements and 3 aspherical elements. The focusing distance is only 28cm which, in combination with the f/2.4 light and 9 rounded aperture blades, make the lens stand out with extremely smooth bokeh with an amazing perspective. You compose the frame – we will take care of the rest!

Blackstone – Reinforced full-metal construction. All lens markings are engraved and filled with a UV-reactive paint enabling easy focusing in dark enviornments. Included with the lens is a hard case.

Intelligent Lens Design
The Irix 15mm f/2.4 lens has a module that allows you to control the lens’ iris directly from the camera, thanks to which popular semi-automatic modes (PASM) and data recording in EXIF format are available. The use of electronics also enable the lens to be equipped with a focus confirmation system – the camera will announce the correct focus setting (either in the form of an icon in the viewfinder or with a sound), every time you set the focus correctly – it’s easy and convenient! It’s worth noting that Irix lenses have the appropriate correction profiles that are pre-loaded and readable by software (such as Adobe Lightroom and Adobe Photoshop), that will make your shooting experience even more enjoyable.

Additional Features

• Click at infinity – enables precise, easy, and quick focusing. During focusing, you will feel the exact moment when your lens sets to infinity, which is extremely useful when shooting in difficult lighting conditions (i.e. at night).
• Focus Lock – allows you to lock the focus ring in a specific position, which is extremely beneficial when you want to keep a specific focus plane i.e. in astrophotography, or when using the hyperfocal scale.
• 95mm front filter thread – allows you to use screw-in filters such as Irix Edge UV & Protector, Irix Edge Circular Polarizer, Irix Edge ND, and Irix Edge Light Pollution filter and others.
• Compatible with Irix Edge IFH-100 Filter Holder – allows you to expand your creativity thanks to Gradual Neutral Density filters with different gradients: Soft, Hard and Reverse
• Rear Gel filter slot – allows the use of Neutral Grey filters mounted on the rear of the lens, which is a unique feature of the Irix 15mm f/2.4 and Irix 11mm f/4.0 lenses.
• Circular Polariser Adjustment Window – the lens hood is equipped with a sliding window, allowing you to freely rotate the polarizing filter without the risk of getting dirty.
• Focus Calibration window – due to the specifics of focus detection in DSLR cameras based on phase detection,  it may sometimes happen that the lens needs to sync with the camera. Thanks to this special opening, you can easily calibrate the lens at home using basic tools within 5 minutes. Fast, simple and effective!
